Studies of Welfare Populations: Data Collection and Research Issues. The Value of Rich Sampling Frames

06/01/2002

The list of the target population (or the materials used to construct a list) is a tool to assure that a probability sample will offer a useful description of the full population. When the designer acknowledges that nonresponse inevitably will occur in the survey, the frame takes on new value. When the designer has a choice of frames (e.g., a list frame from a social welfare agency containing data about the persons prior income and employment experience, an area frame, a random digit dial frame), evaluation of the frame must include both coverage and nonresponse issues. Coverage, the extent to which the frame includes all target population elements and nothing else, is an important attribute.

Sampling frames that contain information beyond simple identifiers can help reduce nonresponse error. If the frames include data on prior addresses, then those with a history of moves might be identified as likely movers, with higher than expected locating effort. If frames contain data on use of agency services in the past, the data might be used to customize approaches to sample persons in an effort to address potential interests and concerns about survey participation (e.g., having interviewers explain the importance of the survey to measuring the well-being of former food stamp recipients). Sometimes data exists that are correlates of key survey variables (e.g., participation in types of programs [higher correlated with current statuses like work training programs]). Such data might be useful in assessing nonresponse errors and building weighting adjustment or imputation models.
